Enzooty of non-Hodgkin's malignant lymphoma of Papio hamadryas in Sukhumi monkey colony. Clinical and morphological signs of pre-lymphoma.

Inoculation of hamadryas baboons with blood of leukemia ill people-induced malignant non-Hodgkin's lymphoma in experimental animals for a very considerable latency period. At close contact of inoculated baboons with healthy non-inoculated animals, the lymphoma spread between them. The epidemiological analysis, postmortem examination, histological analysis, tissue culturing, and PCR were used for the diagnostics of lymphoma and pre-lymphoma, purification, identification of STLV-1, and HVP viruses.

Isolation and genetic characterization of encephalomyocarditis virus 1 from a deceased captive hamadryas baboon.

In 2007, numerous hamadryas baboons (Papio hamadryas) died suddenly in an aviary of a primate institute in Sochi, Russia, in the absence of prior clinical signs. Necropsies were suggestive of encephalomyocarditis virus infection, but RT-PCR assays with commonly used primers were negative. Here we report the histopathological results obtained during necropsies and the isolation and genomic characterization of a divergent strain of encephalomyocarditis virus 1 (EMCV-1) from heart tissue of one of the succumbed hamadryas baboons.

An enzootic outbreak of acute disease associated with pathogenic E. coli in Adler monkey colony.

Background: In spring 2009 in Adler colony of the Institute of Medical Primatology, a large enzootic outbreak of acute intestine infection associated with pathogenic E. coli occurred and caused 5% mortality of population (209 animals).

Methods: The epidemiological analysis, bacteriological investigation, postmortem examination, histological analysis, and PCR were used to identify the infectious agent.
